Primary synovial chondromatosis of the elbow.

Very few cases of primary synovial chondromatosis of the elbow have been reported in the literature. This is a study concerning the late outcome of primary synovial chondromatosis in the elbows of 12 patients, 10 men and 2 women, with a mean follow-up of 16 years 10 months. The average age at the time of the initial complaint was 29 years. The histories of 10 patients revealed elbow strain as a consequence of work-related activities. Surgery included removal of loose bodies and partial synovectomy in all patients. A moderate to severe osteoarthritis was found preoperatively in 5 of 12 patients and during follow-up in 7 of 10 patients. The degree of osteoarthritis deteriorated after surgery in 5 of these cases, depending on patient age, length of presurgical history, length of follow-up, and strenuous activities. However, the functional deficiencies were usually moderate and had little significance with respect to the activities of daily living. No recurrence of primary synovial chondromatosis was found.

A qualitative analysis of family member needs and concerns in the population of patients with burns.

The importance of family support to ameliorate the recovery of a patient with burns has been documented in the literature. However, there is a dearth of research that identifies family members' needs and concerns during the hospitalization of patients with burns. Study aims were as follows: (1) identify support needs and concerns of family members of adult and pediatric patients currently in a burn center and (2) explore the relationship between family needs and the patient's severity of injury. An observational design was used that incorporated semistructured interviews with family members 1 to 3 days after the burn. A convenience sample of family members of burn center patients (n = 97) was recruited over 9 months. Content analysis was used to establish themes from interview data. Interrater reliability on coding of thematic units from 15% of the interviews was 86%; discrepancies were corrected to 100%. The average family member was 42.3 years old, female, white, and at least a high school graduate. Family members' concerns included general patient concerns, physical concerns about the patient, satisfaction of personal needs, and psychologic concerns about the patient. Major sources of support were family and friends, burn center staff, and spirituality. Family members of pediatric patients identified pain and skin graft surgery as priority worries. Satisfaction of personal needs, financial support, and information needs were greater among family members of intensive care unit patients in comparison with step-down patients. These findings underscore the importance of communication and reassurance between the burn team and the family members. Alterations to the support provided to families can be made on the basis of study subjects' responses.

An in vitro evaluation of the marginal integrity of a porcelain inlay system.

There is currently no consensus of opinion regarding form of the finish line for porcelain inlays. This study compared beveled and nonbeveled finishing lines. Twenty-four Class II MOD cavities of a standardised design were prepared in extracted premolar teeth. Twelve were finished using a half enamel occlusal bevel and 12 were not beveled. Porcelain inlays were fabricated and luted with a dual-polymerizing resin material. The completed restorations were stored in water, thermocycled, and analysed using a scanning electron microscope. The quality of the enamel/composite resin interface was found to be considerably better than that of the inlay/composite resin interface. The adaptation of composite resin to enamel was of equal quality for both beveled and nonbeveled preparations.
